But if you geared down one motor, when applying the ball to the system, one motor has more torque that gives more resistance to the ball's inertia. But at the same time, the other motor takes the same resistance to the ball's inertia, but has less torque than the geared down motor so it slows down more and gives the ball an odd trajectory and speed and backspin.
